Probabilistic design of the Land Barrier on the Bolivar Peninsula, Texas

The Houston Metropolitan area is a hurricane prone area and vulnerable to flooding by large storm surges caused by these extreme storm events. The area is a major economic center in the State of Texas and even the whole United States. Protection of the area against flooding is extremely necessary to protect the economy, community and environment...

Guidance on erosion resistance of inner slopes of dikes from 3 years of testing with the Wave Overtopping Simulator

The Wave Overtopping Simulator was developed in 2006 and destructive tests have been performed in February and March of 2007, 2008 and 2009 and will probably be continued in 2010. The tests show the behaviour of various inner slopes of dikes, embankments or levees under simulation of wave overtopping, up to a mean overtopping discharge of 125 l...

Velocity and flow depth variations during wave overtopping

Nowadays the protection of our country for high sea levels and heavy storms is daily news. The ComCoast project (COMbined functions in the COASTal defence zones) is originated by ten organisations out of five European countries bordering the North Sea coasts in order to develop innovative solutions for flood protection in coastal areas. Instead...

Development of Alternative Overtopping-Resistant Sea Defences: Proposal for concepts

The present proposal deals with a presentation of three potentially feasible concepts for strengthening of the sea defences as to allow for increased wave overtopping, within the framework of ComCoast. In addition, for each concept an indicative proposal is given for a further theoretical study (Phase 2) and an indicative approach is shown for...

Riprap stability on the inner slopes of medium-height breakwaters

Medium height breakwaters are subjected to a considerable amount of overtopping. This implies the armour on the inner slope has to stable against overtopping waves. Existing equations do lack some basic understanding of the process of starting up movement of rock on the inner slopes. In case one relates the stability of the blocks on the inner...

Riprap stability on the inner slopes of medium-height breakwaters

Medium height breakwaters are subjected to a considerable amount of overtopping. This implies the armour on the inner slope has to stable against overtopping waves. Existing equations do lack some basic understanding of the process of starting up movement of rock on the inner slopes. In order to get more insight into this phenomenon a special...

Wrijvingskrachten op het binnentalud van een dijk ten gevolge van golfoverslag en het ontwerp van een schuifspanningsmeter ter meting van die krachten

Hoe evenwichtsverlies bij golfoverslag ontstaat en welke krachten daarbij een rol spelen is onduidelijk. In dit rapport is onderzocht hoe groot de wrijvingskrachten op het binnentalud van een dijk zijn ten gevolge van het overslaande water. Omdat dit probleem niet toegankelijk is voor berekening, zijn een aantal proeven gedaan. Hiertoe is een...
